can f T miliari lil. Dioxinthe Tilniterfl States resoN, lim a f sidingY at L laslri and tit l 'n the county l3n- Y...neas have invented l nseiiul improvement in -urning Bricks of which the y is a iulh clear7 and exact description7 reference being' had to the accompanying); drawings.

rlhis iniy ntion relates to the biu'ning` ot briclrs and has specia1 reference to the means ifor producingi` heat whereby the burning` is effected. The objects of the invention are the provision of brick burning' apparatus whereby therequisite heat can be produced by the combustion oi coal and this with a minimum of manual labor and by the use or" simple and comparatively inexpensive equipment; the provision oi portable coal burning equipment for use outside oi but in conjunction with briclc kilns which shall operate with a min' um of the heat loss with a minimum oi permanent constriution:l the Operation ot coal burning' means for brick kilns which shall obviate the necessity of insertine` ,Fuel side the kilns or the Withdrawal oi: ash 'from the kilns and which shall not interiore with the employment of the gras, oil. other alternative heating agents it desired; the provision of a portable lriln furnace with portable kiln Walls; While further object-s and advantages of the invention will become apparent as the description proceeds.

ln the drawing' accompanying' and torming part oi" this application l have illustrated one embodiment of my said invention although it Will be understood that ll do not thereby lirnit myself to any of the particular constructions therein shown which can he varied very Widely Within the scope ot mv inventive idea. ln these drawings lling. l is a perspective view showing; my im! prove-,ments as applied to a continuous row ci kilns: Q is vertical sectional. view through l 1 lire bor: and one ot the arches oi the kiln. and 3 is a top plan vievv o t said kiln together with the coal burning:

means.

escribing by reference characters the parts shown in these drawings 1-1 represent brick lrilns and 2-2 the arches or eyes which traverse the lower part of the same. These arches ordinarily serve as lire boxes for the combustion of Wood, coal, or gasvq and also as distributingchannels whereby the r ducts of such combustion led to all Y "s ot' the structure through the loosely in brick. ln the present embodiment l have illustrated these kilns as arranged in a row, the eyes or arches extending transversely such rou; and the space between the adjacent kilns being` occupied by downdrait passage-Ways B as described in my former Patent No. uh dated October '19, 1920. The end oi said passage communicartes with the upper part of the lriln at one side and is formed at its lower end with an outlet arch which communicates with the inlet ot portable conduit l Whose side is provided with a plurality oi connections 5 which lead to the arf-hes of the next succeediA e' kiln. .ln this ivay the partially cooled.

njas escaping trom the hrst kiln is employed to preheat the second kiln, and in turn to dry other succeeding kilns until its dew point is reached whereupon it is received in down-turned elbows 6 6 which communicate with an under-ground or other passageway (not shown) leading; to an exhaust tan or other draft producing; appliance. lt will be understood that my invention is not restricted to use with this kind lriln although it oiiers particular advantages in such combination. lt is only necessary tor its economical performance that the kilns should he arranged in a row with their arches transverse ot such rorv and a railroad track Z or equivalent roadway provided at cach side thereof` llpon each oit tl'iese tracks or roadways and opposite each arch l locate an automatic stoler Ul of any suitable type. l prefer to employ one such Stoker tor each arch and to combine a sucient number of the same upon singgle car ll to correspond with all the arches oit a single lilin although a smaller number per car could be employed indeed the cars can be made very short and Aed only one stolrer employed per car. l have here shown tor illustrative purposes a lnln with ve arches and cars with five stokers. but the kilns can be made either longer or shorter as also may the cars. The top of each car is provided with a hopper 12 for the reception of fuel, which is distributed and apportioned by the auger-conveyor 13 to ch annels le leading*` to the different grates 14a, All the `strates are operated by chains l5 trom a shaft lr6 suitably 1@geared to a driving motor 17. The interior of the car body is provided with combustion chambers 18, one for each Grate, the whole forming` a portable furnace; and the side of the car next the kiln is formed with openings 19, one opposite each arch and connected thereto by a movable thimble 2O of heat resistant metal which may either be a hightemperature metallic alloy or a refractory i receive the bricks from the kiln which have 'The crane is )referabl movable to a been sufficiently cooled to handle. 25 represents a travellingl crane movable on tracks 26-26 located above the row of kilns and used for transferring` coal from the car 22 to the hoppers 12 by the aid of a clamshell bucket 27, and also for the manipulation of brick handling devices to build the new kilns and demolish the burned kilns. point completely above the car tracks wherefore the track 26 preferably has one rail outside each railroad track.

l have here shown the sides of the kilns as encased in a scoving made in large portable panels 30-30 as described and claimed. in my application Serial No. 429,610 iled December 10, 1920. This, while not imperative, is of great practical convenience and providesa kiln wherein both the walls `and the furnace are portable, thereby enabling the construction and demolition of the kilnbody entirely by mechanical means and without obstruction of any kind. As a result of my improvement the kilns are built, scored, coule-fl, red, and demolished mechanically, with a minimum of hand labor and a maximum of speed. I prefer and recommend that each-Stoker be of the size and capacity known as 5,0 horse power, that is, of a grate-area sutlicient to consume the amount of coal required per hour to operate a fifty house power boiler.

It will be understood that great changes may be made in detail within the scope of my invention and that I do not limit myself in any way except as specifically recited in the annexed claims.

p Having .thus described my invention what l claim is:

l 1. rllh'e combinationv with a row of brick kilns, of an .automatic coal stroking device movably supported at each side of the row Aand adapted to be presented to said kilns successively in heating relation. y

2. rlheV combination with a row of brick kilns and a lined track therealong, of a portable, coal-burning grate outside of and independent from said kilns, and means for movably supporting' said grate whereby it may be transported along said track from kiln to kiln and presented thereto in heat supplying relation. Y

3. The combination with a row of brick kilns. each having` arches transverse to the length of the row` of automatic coal stokingr devices movably supported one at each side of said row and adapted to be used in pairs, each device having a number of combustion chambers equal to the number of arches iu a kiln and connected one chamber to each arch.
